Mitzi Shore is the mother of many comedians. She was the owner and founder of the Comedy Store where many comedians had their career break.

One of them is Jim Carrey who took on twitter to pay his tribute:

The great Mitzi Shore, owner of the famous Comedy Store, has passed away. No words can express the gratitude I have for her. We met in 1979. She opened the door to my dreams! If she loved you, you did well. If she didnít, you did something else. I will love her forever. ;^) pic.twitter.com/lBNXnW0mEr
